STOPPERING FOR BOTTLES INTENDED TO CONTAIN VOLATILE LIQUIDS.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application field May 4, 1909. Serial No. 493,864.

To all whom it may concern:

Be it known that 1, Jonas BENeUn, of 47 Rue Blanche, Paris, France, haveinvented certain new and useful Improvements in and Relating toStoppering for Bottles Intended to Contain Volatile Liquids, of whichthe following is a specification.

Ethyl chlorid was placed upon the market in 1890 in tubes with atapering capillary spout soldered to them. In order to use it thetapered spout was broken and the tube could only be used once. In 1891the inventor utilized tubes with a metal stoppering permitting of thefractional employment of the ethyl chlorid and hitherto this has beenthe only model employed. These bottles however present a considerabledefect. The hermetic joint is obtained by compressing an indiarubberwasher against the capillary orifice. Now this washer may block thecapillary orifice either by the sulfur powder that it gives off or owingto the decomposition of the indiarubber under the influence of theliquid or again owing to the penetration of the indiarubber into thecapillary orifice under the influence of vigorous compression. Thecutting edges of the orifice act as a punch and cut out a piece of thewasher which blocks the orifice. The result is considerable loss andmuch trouble to purchasers and operators. A doctor may have everythingready for an operation and at the moment of opening the bottle may findit not ready for use and be obliged to operate without an anesthetic orpostpone the operation. In the case of bottles sold abroad thedisadvantage referred to above is still greater because it is increasedby freight and customs charges. Up to the present attempts haveconstantly been made to obviate these defects but without success.

The device which forms the object of the present invention obviates thisgrave defect and is extremely simple.

In the accompanying drawing: Figure 1 shows the bottle stoppered with adevice according to the invention. Fig. 2 shows the stoppering deviceseparately, and Fig. 3 is a detail view of a washer forming a joint.

The indiarubber washer 1 is perforated for the reception of a metal parta composed of a small cylindrical rod shorter than the thickness of theindiarubber washer and of a thin circular plate about 1% millimeters indiameter for example. The point is lodged in the central hole formed inthe indiarubber washer a" and the latter is fixed to the bottom of themetal cap I). hen the cap I) isplaced upon the ring 6 of the bottle dthe disk of the part a covers the capillary orifice. The various causesof blockage are eliminated because the indiarub'ber does not come intocontact with the small capillary orifice. A perfect hermetic joint isformed because the rod of the part a being shorter than the thickness ofthe indiarubber the disk is compressed under the influence of thepressure and the indiarubber washer presses strongly by means of itsparts which are not covered by this plate upon the upper edge of theglass rod compressing the capillary hole and insuring a perfectly tightjoint.

This stoppering device enables a capillary orifice of larger diameterthan the capillary orifice employed for delivering ethyl chlorid inmedical ractice to be stoppered. It may be utilized for ethyl chlorid orother volatile products either mixed or not with medicinal substances orwith perfumery essences.

hat I claim is:

1. In a stoppering device for bottles intended to contain volatileliquids, an elastic packing of india-rub'ber having a hole in the centerthereof, a rod guided in said hole, and a disk at the end of the rod,closing the orifice of the bottle.

2. A stoppering device for bottles intended to contain volatile liquids,comprising a stopper with an elastic packing of indiarubher, saidpacking having a hole in the center of the same, a rod guided in saidhole, and a disk at the end of the rod, closing the orifice of thebottle.

In testimony whereof I have hereunto placed my hand, at Paris, France,this 21st day of April, 1909. JULES BENGUE.

DEAN B. MASON, HENRY SCHWAB.
